1 yard topsoil covers 100 square feet to 3 inches, 200 square feet to 1.5 inches and 300 square feet to 1 inch.
One "yard" of dirt (meaning one cubic yard) contains 46,656 cubic inches. Spread 8 inches thick this will cover 5832 square inches or 40.5 square feet.
You have not said what substance you are using a ton of to cover the asphalt.
One yard will cover 81 square feet 4 inches thick, So 81x40=3,240 square feet if spread 4 inches thick. 36/4=9, 9x3x3=81, 81x40=3,240 If you want it 6 inches thick 36/6=6, 6x3x3=54, So one yard will cover 54 square feet 6 inches thick, And 54x40=2,160 square feet If spread 6 inches thick! Now this is spreading it on thick/DEEP!
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.
36x36x36 inches or 3x3x3 feet or 27 cubic feet. If applied a foot thick, it will cover 27 square feet; 6 inches thick = 54 square feet (e.g.: an area 9 feet by 6 feet); 3 inches thick = 81 square feet (e.g.: an area 9 feet by 9 feet).

1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.

It depends on what "5 thick" is: 5 inches thick, 5 feet thick, 5 yards thick, 5 miles thick etc.
